The right to privacy is the right to be let alone, in the absence of
some "reasonable" public interest in a person's activities, like those
of celebrities or participants in newsworthy events. Invasion of the right
to privacy can be the basis for a lawsuit for damages against the person
or entity violating the right.

The right to privacy is not mentioned in the Constitution, but the Supreme
Court has interpreted several of the amendments as creating this right.
One of the amendments is the Fourth Amendment, which stops the police and
other government agents from searching us or our property without "probable
cause" to believe that we have committed a crime. Other amendments protect
our freedom to make certain decisions about our bodies and our private
lives without interference from the government. The due process clause
of the 14th amendment generally only protects privacy of family, marriage,
motherhood, procreation, and child rearing.
